About the QED Performance Optical Graphite
The Performance Optical Graphite is QED's multi-award winning Toslink digital audio cable. Its polymethyl methacrylate (PMMA) acrylic glass optical fibre comfortably handles the higher bandwidth signals required by multi-channel digital audio links. The cable is optimised for a very low jitter design, reducing digital errors for cleaner audio data transmission.
Features and benefits
Polymethyl Methacrylate (PMMA) acrylic glass optical fibre
The PMMA fibre offers half the signal attenuation per metre of the previous Performance model, making it well suited to multi-channel audio. For HD multi-channel audio applications over 12MHz, see the QED Reference Optical Quartz cable.
Very low jitter design
QED identifies jitter — distortions caused by errors in light transmission — as a key factor in audio signal deterioration. Precision cladding techniques reduce jitter, resulting in a cleaner signal with better dynamics and a wider soundstage.

About the QED QE6604
From our tech experts at CEN
The QED Performance QE6604 Optical Graphite is a 5m Toslink digital optical audio cable, using a PMMA acrylic glass optical fibre with fluorinated polymer cladding and 24K gold plated connectors. It links TVs, CD players, Blu-ray players and games consoles to AV amplifiers, receivers or DACs. The very low jitter design reduces digital errors for cleaner audio data transmission.
Who it suits
The 5m length suits home cinema or hi-fi setups where source and receiver sit on opposite sides of a room. If your components are closer together, the QED Performance QE6603 3m or QE6601 1.5m may suit better.
Our tech experts advise
Keep the minimum bend radius above 9mm when routing this cable to avoid signal loss. It handles standard multi-channel digital audio comfortably; for HD multi-channel applications above 12MHz, a higher-specification cable would be needed. The cable carries a two-year warranty.

Frequently Asked Questions
Q: What can I connect with the QED QE6604 optical cable?
A: It connects the Toslink optical output of a TV, CD player, Blu-ray player or games console to the optical input of an AV amplifier, receiver or DAC.
Q: Is the QED Performance Optical Graphite suitable for HD multi-channel audio?
A: It comfortably transmits the higher bandwidth signals used for multi-channel digital audio. For HD multi-channel audio applications over 12MHz, QED recommends its Reference Optical Quartz cable.
Q: How tightly can the QED Performance Optical Graphite be bent?
A: The minimum bend radius is 9 mm. Avoid bending the cable more tightly than this.
